If HPET was enabled by pci quirks, we use i8253 as initial clockevent
because pci quirks doesn't run until pci is initialized.
The above means the kernel (or something) is assuming HPET legacy
replacement is disabled and can use i8253 at boot.
If we used kexec, it isn't true. So, this patch disables HPET legacy
replacement for kexec in machine_shutdown().

This patch renames the include file asm-x86/iommu.h to asm-x86/gart.h to make
clear to which IOMMU implementation it belongs. The patch also adds "GART" to
the Kconfig line.

This patch provides a new set of functions for managing the descriptor
tables that can be used instead of putting the raw assembly in .c files.
Remodeling of store_tr() suggested by Frederik Deweerdt.
